Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 562, here are decompositions:
- 5 + 557 = 562
- 41 + 521 = 562
- 53 + 509 = 562
- 59 + 503 = 562
- 71 + 491 = 562
- 83 + 479 = 562
- 101 + 461 = 562
- 113 + 449 = 562
Showing the first eight; more decompositions exist.
